A few months ago I decided to do a comparison between DJI Go 4 and Litchi AS I SEE IT. If either software package had a feature, I would give that feature a score of 2. If the other software had a similar feature but was, IN MY OPINION, not as good, I would give a score of 1. Here is what it looked like to me. If I have made any errors, let me know but keep in mind, this is how I evaluated these programs. I have to say, I was pretty surprised that there was such a large disparity. Another thing, not scored. As you can see by my Signature, I have two drones. I can fly both of them with Litchi but cannot fly both of them with DJI software.
